I love how the organization (Ainge, Stevens) goes about developing their youth. Guys like Rozier are just scratching the surface, sort of like Avery Bradley was doing when he came into the league.
Fans won't like it, but it's the right approach. Fans will say they stink, or get rid of them, sort of like they did with Bradley.
Ainge knows better though. He will get rid of them for the right deal, all star package, etc. But these guys have more value than people on here think.
